PETG thermal shrink film is a novel type of packaging material that offers excellent recyclability, non-toxicity, and odorlessness. Being part of the polyester series along with plastic bottles, PETG possesses unique advantages in terms of recycling and is internationally recognized as an environmentally friendly thermal shrink packaging material. In certain countries, PETG has replaced traditional PVC products and emerged as a favored choice in the packaging market. As a label’s thermal shrink film, it necessitates exceptional shrinkage performance, wear resistance, weather resistance, and printing capabilities. Compared to other materials, PETG thermal shrink film exhibits high limit shrinkage rate, low natural shrinkage rate, remarkable transparency and glossiness as well as outstanding printing color quality. It finds extensive applications in various sectors such as beverages, food items, cleaning supplies, cosmetics products kitchenware & bathroom accessories. Based on its contractility properties, PETG films can be categorized into high and medium shrinkage film.
